Organisms that eat both plants and animals are

• A. Detritivores
• B. Omnivores
• C. Decomposers
• D. Scavengers

Answer: (B)

Omnivores are organisms that eat both plants and animals. This mixed diet lets them exploit producers like algae or aquatic plants and prey such as small invertebrates or insect larvae, which is common in freshwater ecosystems. The flexibility helps them cope when one food source is scarce, keeping energy flowing through different parts of the food web. Detritivores focus on detritus (dead organic matter), decomposers break down organic material into nutrients, and scavengers feed mainly on carrion; these roles don’t describe feeding on both plant and animal matter, so the omnivore classification fits best.
